COMPARISON OF NON-VIRAL TRANSFECTION METHODS IN MELANOMA CELL PRIMARY CULTURES
2000
Abstract Melanoma primary cultures were transiently transfected via electroporation and lipofection for comparison. Transfection efficiency was superior with electroporation (58±9%) as compared to lipofection (23±9%) as determined by enhanced green fluorescent plasmid (EGFP) transfection. Secretion of IL-2 persisted for up to 3 weeks after electroporation. The increase in sensitivity against immunologic effector cells by transfection with IL-2 was not significant. Our results show the feasibility of a gene tranfer into primary human melanoma cells, different from retroviral transduction.
